If a Axle Shaft boot has failed, the entire shaft assembly must be replaced as boots are not serviceable separately. To remove, start by removing the wheel cover or hub cap and break the Axle Shaft/hub nut loose with a socket and large breaker bar. Block the front wheels to prevent the vehicle from rolling. Loosen the wheel lug nuts, raise the rear of the vehicle, and support it securely on jack stands. Remove the wheel. Remove the Axle Shaft/hub nut and discard it. Drain the gear lubricant from the differential. Disconnect the driveshaft from the differential and remove the rear exhaust pipe and muffler. Pry the inner CV joint out of the differential just far enough to release the snap-ring. The Axle Shaft can't be removed from the differential until the differential has been lowered. Support the differential with a floor jack. Remove the mounting fasteners securing the differential to the crossmember and differential mount. Carefully lower the differential enough to separate the Axle Shaft(s) from the differential. Pull the Axle Shaft out of the hub flange. If it sticks, tap it out with a soft-faced hammer. Installation is the reverse of removal, noting the following points: Remove the rubber isolation washer from the outer CV joint stub shaft and inspect it. Replace it if necessary. Tighten the differential mounting bolts to the torque. Install a new Axle Shaft/hub nut. Tighten the hub nut securely, but don't try to tighten it to the actual torque specification until you've lowered the vehicle to the ground. Fill the differential with the type and amount of lubricant specified. Install the wheels and lower the vehicle to the ground. Tighten the wheel lug nuts to the torque. Tighten the Axle Shaft/hub nut to the torque. Install the wheel cover or hub cap.

Where an axle shaft boot has been damaged, the entire shaft assembly has to be replaced as boots cannot be repaired individually. To remove the axle shaft, first, there is the wheel cover or the hub cap depending on the manufacture of the car, one will have to remove this before he/she can remove the axle shaft/hub nut using a socket and a large breaker bar. Put the front wheels in the fixed position, as it stops the rotation of the wheels, and then free the wheel by removing the lug nuts on the wheel, raise the car with the jack and put it on the jackstands and then remove the wheel. Subsequent steps include the removal of axle shaft/hub nut and the reduction of gear lubricant in the differential and the separation of the driveshaft from the differential but ensuring that it does not hang by the centre support bearing. Take off the rear exhaust pipe and muffler, then use a pry-bar to pull the inner CV joint out of the differential to the extent that you can remove the snap ring, which should be done with the thought in mind that the axle shafts cannot be withdrawn until the differential is lowered. Place the vehicle on a lift, remove the bolts and nuts which fix the differential to the cross-member and supporting bracket, and then lower and angle the differential so as to release the axle shaft(s). Withdraw the axle shaft from the hub flange using a gentle force; use a soft-faced hammer on it if it gets stuck. For installation, there is a taper pin or a retaining ring that is used to retain the inner CV joint stub shaft and should be replaced with a new one. As with the initial steps in the procedure, operate in the reverse order of removal, check the condition of rubber isolation washer installed on the outer CV joint stub shaft and replace it if needed. Screw in the differential mounting bolts to the required torque then fit new axle shaft/hub nut and only tighten without reaching the actual torque up until the vehicle has been lowered on the ground. Add the right type and quantity of lubricant into the differential and fit the wheels; lower the car, then torque the wheel lugs to the prescribed amount before finally doing up the axle shaft/hub nut then replace the wheel cover or the hub cap.

Carefully lower the differential enough.
